[0034] Reference Figure 2 The rear end of the shading cloth 42 is fixedly connected to the front surface of the sliding rod 43. A threaded groove is provided on the outer wall of the sliding rod 43 near the top of the shading cloth 42. A threaded sleeve 41 is threadedly connected to the outer wall of the threaded groove. After the sliding rod 43 is moved to unfold the shading cloth 42, the threaded sleeve 41 is rotated to be threadedly connected to the threaded groove, so that the threaded sleeve 41 can move upward and squeeze the bottom end of the fixing ring 2 to limit the sliding rod 43.

[0035] Reference Figure 1 - Figure 3A positioning block 21 is fixedly connected to the rear surface of the tank body 1, and a threaded rod 23 is threadedly connected to the rear surface of the positioning block 21. By rotating the threaded rod 23 and threading it with the positioning block 21, the threaded rod 23 can drive the guide rod 24 to move, and the guide rod 24 drives the inclined guide block 1 25 to move, and the guide block 1 25 drives the guide ring 29 and the inclined guide block 210 to move. The movement of the guide block 210 can drive the connecting block 1 27 and the scraper 26 to move, so that the scraper 26 can be released from contact with the inner wall of the tank body 1.

[0036] Furthermore, the guide rod 24 is fixedly connected to the front surface of the threaded rod 23, and the front end of the guide rod 24 is slidably connected to a guide block 25, which is arranged to be inclined so that the guide block 25 can be driven to move by the guide rod 24 moving outward, and the bottom end of the guide block 25 is fixedly connected to a guide ring 29, which can drive the guide block 210 to move, and the guide ring 29 is rotatably connected to the outer wall of the rotating rod 5, and the guide ring 29 will not rotate with the rotating rod 5, and the guide ring 29 can move up and down.

[0037] Furthermore, the bottom end of the guide ring 29 is slidably connected with a guide block 210 and multiple groups are provided. When the guide block 210 rotates, it will slide on the bottom end of the guide ring 29. The guide block 210 is arranged in an inclined shape, so that the inclined guide block 210 can drive the connecting block 27 to move. The guide block 210 penetrates and is slidably connected to the top of the support plate 28. The bottom of the left end of the guide block 210 is fixedly connected with a connecting block 211. The guide block 210 drives the connecting block 211 to move. The bottom end of the connecting block 211 is fixedly connected to the top of another group of guide blocks 210.

The connecting block 27 can be moved by setting the guide block 210 in an inclined shape.

[0038] Working principle: When in use, the motor drives the rotating rod 5 to rotate, and the rotating rod 5 drives the supporting plate 28, the connecting block 27, and the scraper 26 to rotate. The microalgae or other biological substances attached to the inner wall of the tank body 1 can be scraped off by the rotation of the scraper 26, thereby reducing the substances attached to the inner wall and keeping the tank body 1 clean. At the same time, the nutrients and gases in the water can be exchanged with the microalgae cells more smoothly, thereby promoting the growth and metabolism of the microalgae.

[0039] By rotating the threaded rod 23 and threading it with the positioning block 21, the threaded rod 23 can be moved outward to drive the guide rod 24 and the guide block 1 25 to move. By setting the guide block 1 25 to an inclined shape and the guide rod 24 to be slidably connected to the inner wall of the guide block 1 25, the guide rod 24 can pull the guide block 1 25 to move downward, driving the guide block 210 to move downward. By sliding the connecting block 1 27 to be connected to the inner wall of the guide block 210 and the guide block 210 to be inclined, the connecting block 1 27 can be moved inward to drive the scraper 26 to move, thereby releasing the contact with the inner wall of the tank body 1, thereby preventing the scraper 26 from always rubbing against the inner wall of the tank body 1, causing the tank body 1 to be worn and damaged, thereby increasing the service life of the tank body 1.

[0040] By rotating the threaded sleeve 41 and threading it with the outer wall of the upper end of the sliding rod 43, the threaded sleeve 41 moves to release the limit on the sliding rod 43. At this time, the sliding rod 43 can be moved to pull the blackout cloth 42 to unfold. By unfolding the blackout cloth 42, the tank body 1 can be covered, and the amount of light received by the tank body 1 can be controlled, thereby creating a lighting environment most suitable for the growth of microalgae. At the same time, excessive light is prevented from causing photoinhibition or photodamage to the microalgae cells, affecting their normal growth and metabolism, thereby improving the effect of cultivating microalgae in the tank body 1.
